Description

This RX Preamplifier module BOX with 2N5109 transistor is based on W7IUV design. You can use it as high IP preamplifier for RX antennas (beverage, DHDL, flag etc.). Gain is up to 18 dB and there is also build in variable ATT. You can easy set the gain as high as you need! As well you can set right transistor bias with multi turn potentiometer. Two relays offer bypass switching if there is no power supply voltage. You can use external power supply connected to the box or the bias tee box for power over the coax.


Using

  • High IP RX preamplifier - RX antennas
  • Buffer amplifier
  • Driver amplifier

Something to do on a Sunday afternoon while it's raining outside all day. The preamplifier and the BIAS-T are already soldered. Remoteqth.com & QRO.cz kits are always fun to assemble. You could also buy them complete, but that way you also have a sense of achievement.
